I’ve noticed low water pressure in our home. What could be the cause?

Low water pressure can be a nuisance and is often the sign of a bigger issue in your plumbing. It’s important to figure out the problem so a solution can be implemented.

You could have mineral buildup from the deposits that water leaves behind. Even a small amount can create blockage and could be what causes low water pressure. If your pipes are old, you could also have natural corrosion buildup, which tends to block the flow of water.

It is also possible that you have a leak somewhere in your home's plumbing system. This will reduce water pressure throughout the home because if the water isn’t coming through the pipes, it’s going somewhere else.

Sometimes low water pressure has nothing to do with your own piping system. It may be from a failure in your area's municipal water supply. Roto-Rooter can help find the cause and troubleshoot low water pressure in your home.

Is there anything we can do to determine what is causing the low water pressure?

There are a few things you can do: Check the main shut-off valve to make sure it is open all the way. Also check to see if there is a leak in the main, and inspect pipes in your basement or garage for evidence of a leak.

If the low pressure is specific to a fixture, check your faucets. You may have a clogged aerator or a clog to the line in the sink. The same goes for your shower head. You could have a clogged nozzle.

If you experience low pressure only from the hot water outputs in your home, it is likely a problem with your water heater.
